yeah these do really good, especially if you are being conservative on the throttle If you keep it around 20mph and under you can get at least 50 miles out of it, maybe even 60 at top speed in eco (28 mph) you can get around 45 miles and in sport mode probably 15-30 miles depending on speed
I would join the facebook group There's a ride every saturday, including today. If you are interested they leave from gasworks park at 7:30 sharp (I think they start meeting up around 7pm) and the ride is like a 15 mile or so loop
